“There is no more pressing, or defining, global challenge than climate change,” said Walsh in a statement. “We know we must be making investments now to create a more sustainable future for the world we share. I look forward to continuing these substantive, challenging conversations in Boston.”

The leaders will discuss and share experiences with building low-carbon, climate-resilient communities.

Walsh is on the steering committee of the C40 Cities Climate Leadership Group, an organization that works with more than 80 of the world’s cities to tackle climate change. The group’s first summit took place last September in Los Angeles, where a “US-China Climate Leaders Declaration” was signed, signifying a commitment by major Chinese cities to peak CO2 emissions earlier than the 2030 goal. This week, in Beijing, the Chinese cities of Dalian and Chengdu joined C40, strengthening the coalition’s world force, said Walsh.

Boston is part of the Compact of Mayors, a global coalition of more than 500 mayors and city officials, who pledge to reduce local greenhouse gas emissions, enhance resilience to climate change, and track progress transparently. Boston has committed to reducing greenhouse gas emissions by 25 percent by 2020 and 80 percent by 2050. Boston also received an international award for community engagement at the United Nations Climate Change Conference in Paris last year.
